Nice thread, I've been reading it and trying to figure out what's wrong with my aquarium...
So just to be clear what I need to do is: have a filter (in my case a DIY canister) with SPONGE, CARBON and BIO MEDIA (like ceramic rings, somewhere where the "good bacteria" needs to grow)? Please correct me if I'm wrong? Also the more the bio media, the better right?
Thanks!
Could you describe your problem a bit to us?
In general yes... a good canister with adequate mechanical (sponge), chemical (carbon or better yet purigen), and biological filtration (bio media provides added surface area for nitrifying bacteria to colonize). You also need a pretty good flow rate from your canister. You want to be turning your entire tank volume over about 5x an hour. So for example a 100 gallon tank needs a pump that will AT LEAST do 500 gallons per hour at head.
You really cannot have too much bio filtration. Well you can, but the only thing it will hurt is your wallet. Nitrifying bacteria will colonize and reproduce to match their food source, ammonia. As the ammonia spikes so does the amount of bacteria (your bio filtration). As levels decrease the bacteria follows right along. So technically it is possible to get a HUUUUGE filter and fill it with tons and tons of bio media. Having too much bio media won't harm your tank, but it might not all be useful if there isn't enough food source to sustain a bacteria colony that large.
For a turtle setup, most canisters have a set amount of mechanial or sponge filtration. Purigen or Carbon have ratings... ie 100mL will handle 100 gallons or whatever. Use that amount. Fill the rest of your canister up with bio media if you can afford to.
